Rudolph was an original member of the family musical group that consisted of him and his brothers O’Kelly “Kelly” Isley Jr. and Ronald Isley. 

The R&B and soul band took off in the late 1950s and continued to make music for over six decades. 

They are responsible for the timeless hits “Who’s That Lady?,” “Between the Sheets” and “Shout.”

Rudolph left the band in the late 1980s to pursue a life in the ministry. In 1992 the band was inducted into the Rock and Roll Hall of Fame. Last year, the group was inducted into the Songwriters Hall of Fame
